SAW-HANDLE.

Specification of Letters Patent.

Patented Mar. 14, 1911.

Application filed October 12, 1909. Serial No. 522,222.

To all 'whom it may concern:

Be it known that I, JAMES FRANnLiN MIXoN, a citizen of the UnitedStates, residing at Manatee, in the county of Manatee and State ofFlorida, have invented new and useful Improvements in Saw-Handles, ofwhich the following is a specification.

The present invention provides a handle for hand saws designed mostJespecially for lubricating the saw blade to facilitate the operation ofthe Saw and prevent its sticking by binding against the Sides of thekerf.

The invention contemplates a chambered handle adapted to contain aquantity of lubricant and a valve mechanism for regulating the outflowof the oil as may be desired chambered and Supplied with the several.

may be desired to insure easy working of the saw when in operation.

The invention consists of the novel features, details .of constructionand combinaA tions of parts which hereinafter will be more particularlyset forth, illustrated in the accompanying drawing and pointed out inthe appended claim.

Referring to the drawing forming a part of the specification-Figure l isa view in elevation of the rear portion of a saw blade and handleembodying the invention, Vone half of the handle being removed andshowing fastening means in sections. Fig. 2 is a top plan view of theparts illustrated in Fig. l. Fig. 3 is a section of the handle on theline 3-8 of Fig. 1. Fig. 4 is a sectional detail on the line 4-4 ofFig. 1. v

Corresponding and like parts are referred to in the followingdescription and indicated in the views of the drawing by the samereference characters.

The invention is designed most especially for hand saws such as used bycarpenters .and journeymenV for lubricating the saw blades, therebyovercoming the practice generally in -vogue by lubricating the saw bladeeither The handle is hollow 'or chambered as indicated at 2, Saidchamber constituting a reservoir to receive a quantity of oil. Thehandle may be of any construction and preferably consists of similarsections or parts 3 which are placed together and secured in any manneras by fastenings 4 which are passed through openings formed transverselyin the parts 3. The meeting faces of the parts or sections 3 are formedin a manner to secure a closed joint so as to prevent waste of oil.

In the preferred construction the handle is formed of metal and is castin sections for the sake of simplicity and cheapness.

It is to be understood that the handle'may be provided in any manner solong as itis openings and adjunctive parts.

The forward port-ion of the handle is reduced in thickness as indicatedat 5 and its reduced part receives the upper rear portion of the Sawblade 1, which is held in place by the fastenings 4 passing throughopenings thereim Shoulders 6 are formed at the in ner end of thereducedportion iand Said shoulders are arranged at a right angle t'o the backof the saw, thereby enabling the same to' be used in the capacity of asquare. An opening is formed in the upper rear portion of the handleleading into the chamber 2 and is closed by means of a plug 7, saidopening admitting of oil being supplied to the chamber 2. A groove isprovided in a side of the plug 7 to form a vent for the admission of airwhen oil is discharging from the handle. An opening S is formed in thelower front port-ion of the handle and constitutes an outlet for theoil, Said opening being tapered and provided with a seat for a valve 9.Grooves l() are formed in the meeting faces of the parts or sections 3and communicate at their inner ends with the opening 8. When the valve 8is unseated the oil passes from the chamber 2 of the handle through theopening 8 into the grooves or ducts 10, thence to the saw blade so as tolubricate the same.

A stufling box is provided at the upper forward portion of the handleand receives the upper portion of a stem l1 provided at its lower endwith a valve 9, the projecting end of the stem 11 being connected to thefront end of a lever 12 which is mounted upon the back of the handle 2and arranged in a recessI 13 formed. therein. The lever 12 .is connectedto the back of the handle by means of a pin or bolt 14C. To prevent theends of the pin or bolt 1.4L projecting beyond the outer sides of thehandle the saine are recessed in line with the pin 14 as indicated at15. The stulling boX consists of a sleeve 16 threaded into an openingformed in the back of the handle, and a gland 17 which is threaded intothe sleeve 16 and serves to confine a packing 1S. A coil spring 1) ismounted upon the stem 11 between the valve 9 and the gland 17 and exertsa downward pressure upon the valve to hold the same seated.

In practice the plug 7 is removed and a quantity of oil supplied to thechamber 2 after which the plug is replaced. When the saw is in operationthe blade generally assumes an upright position and when it is requiredto lubricat-e the same the lever 12 is operated and unseats the valve 9,thereby permitting a similar quantity of oil to pass from the chamber 2through the opening S and ducts 10 to the blade. Upon releasing thepressure upon the lever 12 the valve 9 is automatically seated by theaction of the sprin 19, thereby shutting off further discharge of theoil.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation will be readily apparentto those skilled in the artto which the invention appertains, and While I have described thcprinciple of operation of the invention, together with the device whichI now consider to be the best embodiment thereof, I desire to have itunderstood that the device shown merely illustrative, and that suchchanges may be made when desired as are within the scope of the claimappended hereto.

Having thus described the invention what is claimed as new, is

A lubricating handle for hand saws, said handle being chambered andcomprising similar parts each having a recess in one side and having itsforward portionbfl'set, the two sections when placed together having anoil chamber between them and receiving the saw blade between the oifsetforward extensions, the handle having an oil opening in its lowerforward portion and oil ducts leading from said opening, a springactuated valve for closing the oil opening, a

lever mounted in a recess formed in the back of the handle and havingconnection with the stem of the valve, and a plug for closing a fillingopening in the upper rear portion of the handle, said plug having a ventopening.

In testimony whereof I affix my signature in presence of two witnesses.
